Symmetric vs Asymmetric Overview
Understand the two main families of modern cryptographic systems.
Welcome
In this lesson we compare the two main families of modern cryptography: symmetric (shared-key) and asymmetric (public-key) encryption.
Symmetric Encryption
In symmetric encryption, the same key is used for both encryption and decryption. Examples: AES, ChaCha20. It is fast but requires secure key exchange.
